rI-he present invention relates to devices for exterminating pests whereina poisonous liquid insecticide is fed fromA a container inan oozing manner to a point accessible to crawling insects; Such insects may thus be poisoned by actual' contact with thepoisonous material or from feeding thereupon. It is an important object of the present invention toimprove upon the structure disclosed in my co-pending applicationA Ser. No. 71.13339 filed February 1'5-, 1934 by changing the stabilizing feae ture of the device from the body portion tothe capi portion thereof; This improved stabilizer may be constructed in a detachable manner or made integral with the cap, as desired. By preference, in the present invention, it is shown as a separate part afxed to the cap.

It is an object of the invention to provide an improved nozzle whereby the stabilizer per se is united to the cap and. at the same time provide a suitable holding means for a wick thru which the liquid may be gradually dispensed for the pests to feed upon.

It is also an object of the invention to provide a suitable sealing cap which is integralized with the cap and. stabilizer having both a vent and a discharge opening.

A still further object of the invention is to provide, as a new article of manufacture, a poisondispensing closure device applicable to conventional fruit jars now on the market.

Other improved construction features may become apparent after reading the disclosure which follows.

Referring to the accompanying drawing wherein the above features are shown,

Fig. 1 is a longitudinal mid-section of the device With the nozzle cap shown in a detached relation.

Fig. 2 is a front end elevation of the device showing the device in operative position.

Fig. 3 is a perspective View of the sealing cap and shield therefor.

Fig. 4 is a perspective view of the cap and stabilizer with a portion broken away to show the inside end of the nozzle.

Referring in detail to the drawing, as a new article of manufacture, the invention comprises a closure member or cap 5 having an internally threaded peripheral flange 6 adapted to screw onto the externally threaded mouth portion 'l of the jar or container 8. Said closure member also includes the delivery nozzle 9, its cap I0 and a conventional gasket disk Il which engages the inner face of the cap 5. The nozzle 9 is shown having'a'peened'over inner end |25. Said nozzle 9 is preferably made of a non-corrosive sheet metal. overlying said disk il is a disk la. which may be termed a vent disk as it is designed to permit sufficient air to enter the jar to relievey atmospheric pressure as the poison is` dispensed. Said disk I4 is provided with a radialfvent slot t5 which opens out thru the periphery thereof, and. also has av circular aperture |51 which fitsaround the peened end l2 of the tubular nozzle 91 Another accessory of the closure member 5 is the stabilizing piece or foot piece 2li.` whereby the recumbent container` 8i is. maintained in the proper non-rolling operative position. Said stabilizing piece consists of a quadrilateral plate having a broadly U-shaped iiange 2| along the margins thereof. The stabilizing member 20 has an aperture thru the face portion thereof which tightly receives the nozzle 9 and thereby holds said member 20 insuring contact with the end of the cap 5. The foot flange 22 extends in a tangential relation to the cap as a whole. The function of the member 2li is to keep the poison containing jar 8 in the proper recumbent operative position, as shown in Fig. 2, wherein the delivery nozzle is located in the lowest possible position and its inner end is completely submerged by the liquid poison 23 until said poison has nearly all been dispensed.

When the poison filled container 8 is delivered to the trade in a filled condition, it is desirable that an inner disk or circular gasket 24 be provided to prevent leakage around the vent disk I4. Said gasket 24 is desirably provided with a semicircular ear or nap 25 whereby traction may be manually applied to gasket 24 for removing the same preparatory to placing the container in its operative, recumbent position. The inner face of gasket 24 is preferably provided with an adhesive coating.

The poisonous substance 23 should be of a sufficiently fluid character to insure its proper delivery thru the nozzle 9 and said poisonous substance may be of a kind that will be fatal to insects that touch it, even if they do not actually imbibe any appreciable quantity of the same.

The nozzle cap I0 will fit sufliciently tight to insure that it will stay in place during shipment.

Within the nozzle 9 is closely fitted a cylindrical wick 27 having a protruding end portion 28. After the cap Il] has been removed the protruding portion of said wick, which is saturated with the poisonous liquid 23, brings said liquid within easy reach of insects, it being understood that the poison will be sweetened or otherwise rendered 55 palatable and attractive to the pests to be destroyed.

When it is desired to make the stabilizer piece 20 integral with the cap 5 as hereinbefore mentloned, a portion of the peripheral flange 6 may be pressed out of shape so as to have a similar profile as that when the stabilizer is separately applied thereto forming the unit.

Iclaim:

l. In a device of the kind described, a container, for containing a liquid insecticide, having a feed opening, and a cap for said container, said cap having an internally threaded peripheral ilange a portion of said flange being bulged to adapt it to rest in a stable manner upon a level surface and when so positioned to cause the contents of the container to gravitate to said feed opening.

2. In a device of the kind described, an elongated cylindrical container for containing a liquid insecticide, a closure for said container, a stabilizer for said closure whereby said container is supported in a non-rolling position and a nozzle extending through said closure and stabilizer and uniting the same.

3. In a device of the kind described, a container for containing a liquid insecticide, a detachable cap therefor having a dispensing aperture, said cap having a foot portion to maintain said container in a non-rolling condition when placed upon its side, a nozzle extending thru said aperture and communicating with the interior of said container, a wick occupying said nozzle, and

means to vent said container whereby the n'- secticide will feed thru said Wick.

4. As an article of manufacture, a jar cap provided with an internally threaded peripheral ilange, said cap having a dispensing opening thru its end face and near its periphery, said flange having a portion bent out of shape to engage a supporting surface when applied to a jar, thereby to maintain such jar, when recumbent, in a non-rolling condition.

5. As an article of manufacture, a jar cap having a peripheral ilange, a portion of said ange being threaded and another portion being tangentially ilattened, said flattened portion adapted to serve as a f oot to engage a supporting surface when said cap is applied to a jar, said cap having a dispensing opening near said flattened portion.

6. As an article of manufacture, a jar cap having a dispensing aperture thru its end portion and near its periphery, a dispensing nozzle communicating with said opening, and a foot piece thru which said nozzle extends, said foot piece having a foot flange in tangential relation to said cap and having also anges engaging side portions of said cap to aid in keeping said foot piece in an operative relation to said cap.

'7. As an article of manufacture an internally threaded peripherally flanged jar lid, a portion of which is pressed out of shape and flattened, a nozzle tted into said lid, and a cap for said nozzle.
